In this tutorial i am going to teach you how to control speed of dc motor using stm32 microcontroller and l293d half h bridge control ic dc motors are common motors you see in your housesdc water pumps dc fans toys etc dc motors rotate at a constant speed but their speed can be varied and controlled by utilizing few techniques. Pwm based dc motor speed control using microcontroller circuit design the circuit consists of one 8051 microcontroller and its supporting circuitry related to oscillator and reset l298n motor driver module a dc motor and a few push buttons. The project circuit diagram for four quadrant dc motor speed control with 8051 microcontroller is shown in the below figure in several industrial applications like movement of conveyer belts in the clockwise and anti clockwise direction can be done using four quadrant operation of motors. This paper reports a microcontroller based control system to change the speed and direction of rotation of dc motor armature voltage is varied by pulse width modulation pwm of input dc voltage . Fig1 shows the circuit of the microcontroller based dc motor controller at the heart of the dc motor controller is microcontroller at89c51 port pins p00 through p07 of the microcontroller are interfaced with data pins d0 through d7 of the lcd module respectively
